Available from GWB Machine Tools , it delivers working speeds of up to 25mm per second at reduced load, depending on application and safety requirements.

The press brake is ideal for bending small- to medium-sized high precision parts.

The PPRM is a 35t machine with a working length of 1250 mm. The machine's high production capacity is attributed to a simple working principle.

The press brake ram is supported by springs and uses two single-acting hydraulic cylinders. Each hydraulic cylinder is directly connected with a hydraulic pump driven by a servomotor.

There are no switching valves in the hydraulic circuit and no lapsed time in the ram cycle because of mechanical movement of the valves. The result is higher production rates and greater machine reliability.

The PPRM is designed for efficiency and long production life. The press brake consumes on average 30% less energy than conventional hydraulic press brakes. There are no mechanical components such as ball screws or gearboxes that will exhibit wear from friction and reduce accuracy.

The PPRM's bending force is proportional with the torque of the servomotor, which can easily be controlled for the application.

The bending force can be reduced to 5% of the maximum load, allowing the user to work with small tools without risk of damage.

The machine features a 100mm throat allowing access to both ends of the ram and bed for tool loading.

The machine provides an open height of 385mm, ram stroke of 185mm, backgauge X-axis travel of 500mm and R-axis travel of 200mm.

The press brake is equipped with LVD's easy-to-use CADMAN Express CNC control, a Windows based system with a user-friendly interface for all levels of programming experience.

CADMAN Express makes bending easy with a number of automatic features including automatic calculation of bend allowance, automatic selection of tools based on material thickness and automatic calculation of the lower dead point (Y-stroke).

It features graphical representation of tools, program overview in editor and production modes, graphical representation of tools and backgauge in production mode and an easy method of angle and bend allowance compensation.

LVD's CADMAN-B 3D offline programming software is available as an option that provides graphic simulation of bending sequences, including the back gauge position, tool selection and tool set-up.
